This is where I was pulling the tax revenue numbers from, but it also breaks down tax collections by type (income, corporate, etc.)

Interesting about shipping, since I read a number of articles recently that put it at 18% of Greek GDP. I wonder, could this be related to the spectacular deviations in shipping costs? During much of the decade until 2008, Greek shippers were charging upwards of $110,000 a day per ship. By 2009, the rates for shipping dropped to $5,000, so low in fact that companies saved money by refusing contracts, drydocking ships, laying off workers, etc. Many of these companies showed income only from scrapping older ships for metal. I wonder where one might find a year-over-year comparison of the shipping industry.
